Hey Sauber F1 Team, this video series is amazing. I do have a request for a future topic. In car production, there is typically a team of engineers called Noise, Vibration, and Harshness engineers, whose job is to evaluate the sonic and mechanical characteristics of the car, for an aesthetic and also ergonomic purpose. I would guess that for F1, the aesthetics aren't really a consideration. That being said, does Sauber have a team of NVH specialists, and what (and how) do they contribute to the car? Do they focus on longevity/reliability, or do they bring driver aesthetics into consideration? Are they also responsible for acoustic systems like the radio and driver feedback tones? And lastly, do acoustic tests show up in other, possibly "unexpected" places (like the wind tunnel)? Thanks! -TTA

@sauberf1team 9 жыл бұрын

Thanks for the great feedback, TrackTimeAudio! You're right, noise (or acoustics) isn't a focus of our engineers work. We do care about vibrations, of course, and we do respective calculations/simulation as well as tests on our 7-poste rig. Regarding (driver) communication we use respective radio systems provided by Riedel Communications. The biggest issue there is the placement of the drivers' mic (usually in a pocket on the Nomex balaclava).

Fantastic Video. That technology used today is phenomenal! Even if i think that F1 Aerodynamics today have one Problem - because of all the tools and possibilities the Aerodynamic of a Formula 1 Car is too instabile. All These vortex that are created and the airflow split up into 1000 different airflows is making the cars aerodynamic too complicated and instabile. I think a step back towards the aerodynamic concept of Cars like the F2002 f.e. would make the Cars Aerodynamically as effective but more stabile than the Cars with 1000 different airflows, which are constructed today.

@ShirishPotu 9 жыл бұрын

There is one thing I would like to ask though, - What about the effects of Tire Graining on the windflow? Does that play an important role or could it just be ignored? - Similarly, the Steel Belt is a very smooth one, but the ground isn't. Does that decrease the accuracy of measurements too?

@sauberf1team 9 жыл бұрын

The upper side of the steel belt is coated with a rather rough material, Shirish Potu. The wind tunnel tyres don't react like normal race tyres (wear, graining, etc.). If they did, they couldn't do the mileage described by Willem in the video. But, indeed, it may have negative effects on the track if a car picks up too much rubber in certain critical areas.

@sauberf1team 9 жыл бұрын

Shirish Potu Willem adds - the belt coating we use is synthetic and bonded to the steel belt. It does eventually wear out and become smooth under the tyres. We get tarmac roughness data from Pirelli and use this to help us characterise the roughness we target for the belt coating in the wind tunnel (for our 60% model). The tyres run on the model actually are a bit too smooth aerodynamically speaking but we have ways of experimenting with surface roughness and then apply a small correction to allow for it (really sorry but I am not willing to say exactly what we do!). Anyway another excellent question!

Why isn't the wind tunnel rounded instead of turning vanes in the 90 degrees corners? Because of costs or 90 degrees corners are actually more effective, or because of better wind distribution in the tunnel?

@sauberf1team 9 жыл бұрын

atislav Willem says - To turn the air around the tunnel it is actually better (takes less energy) to use “90” degree corners but with turning vanes. The turning vanes make the air turn evenly because they are spaced quite close together. With a curved tube the air speed would not be so even across the working section. Lots of designs have been tried and tested by the aircraft and aerospace industries both before and after F1 teams started to develop wind tunnels for themselves. They have found the same thing. Excellent question.

@atislav 9 жыл бұрын

Sauber F1 Team Excellent answer, thank you very much guys. I wish you the best for the rest of the 2014 season. I hope regulations will not change much for the next one, so you and other teams will be able to focus on improvements to become more competetive, because you 100% deserve it.

Do you utilize the wind tunnel for vehicles/objects outside of F1?

Regarding the model size, it's surprising that raw material cost is even part of the equation.

You can say publicly you don't test past the restrictions, but I bet privately they all run the tests to the max!

I got a bit confused, before the radiator you stop the swirl or is after the air passess trough the radiaor that it is not longer sppining at macroscopic scale?

@willemtoet_yt 2 жыл бұрын

Swill is stopped immediately after the fan. The radiator then further reduces any that remains.

Thank you, Sauber. The belt does not replicate the tarmac's texture. Why is that?

@willemtoet_yt 4 жыл бұрын

It can, and at Sauber (for Alfa Romeo) we do try to get a match tarmac roughness - but every track is different. Some F1 teams run a smooth belt knowing that it is wrong but do that for improved force measurement repeatability. They then use computer science to predict what happens on track. For each track we get average tarmac roughness values on a macroscopic (stone sizes effectively) and microscopic (little sharp edges and holes) scale. It is measured for the tyre people but is useful for aero too..... :-) So one has to have tricks available to predict how airflow will change as the road gets rougher. One example - aero balance (how much downforce is on the front or rear) changes with road roughness. Why? Because air rushing under the front wing induces a bigger boundary layer if the road is rough.....

I do try to visit universities in my holidays and I do give lectures then. Probably 5 or so per year (take holiday to do it). Plan to do more university work in the next few years when I go part time with money earning work. :-)

@@willemtoet_yt I'm glad to hear that because students most definetely are benefitting from a great lecturer like you, who is also working actively in a very competitive job. Maybe you could add some of those lectures in an online platform like udemy or khan academy for the world to see? I sure would like to dive in from Turkey :)
